Yuav xaiv thiab siv Gas Detectors li cas
1. Paub meej tias hom thiab concentration ntau ntawm cov roj yuav raug kuaj
Gas detectors tau dav siv hauv kev lag luam xws li petrochemicals, kev tiv thaiv ib puag ncig, roj av, thiab cov mines thee. Rau ntau lub sijhawm tsim kev nyab xeeb thiab kev kuaj xyuas qhov xav tau, xaiv lub ntsuas roj tsim nyog yog qhov tseem ceeb rau txhua tus neeg koom nrog kev nyab xeeb thiab kev noj qab haus huv.
Paub meej tias hom thiab concentration ntau ntawm cov roj yuav tsum tau kuaj pom txawv rau txhua lub tuam tsev tsim khoom. Thaum xaiv lub ntsuas roj, nws yog ib qho tseem ceeb uas yuav tau xav txog txhua yam ua tau. Nyob rau hauv qhov chaw mining ntawm thee mines, methane thiab cov tshuaj lom alkanes tsawg dua yog tam sim no, yog li xaiv lub tshuab hluav taws xob hluav taws xob yog qhov kev xaiv zoo tshaj plaws.
Qhov no tsis yog tsuas yog vim hais tias lub hauv paus ntsiab lus ntawm kev tshawb nrhiav cov roj combustible yog qhov yooj yim thiab siv dav, tab sis kuj vim tias lawv muaj cov yam ntxwv ntawm kev saib xyuas yooj yim thiab calibration. Yog tias muaj cov pa phem xws li cov pa roj carbon monoxide thiab hydrogen sulfide, qhov tseem ceeb yuav tsum tau muab rau kev xaiv lub tshuab ntsuas roj uas ib txhij kuaj pom cov pa roj carbon monoxide, hydrogen sulfide, thiab oxygen kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm. Yog tias muaj cov pa roj carbon monoxide ntau dua thiab muaj kev phom sij, xav txog lawv qhov qis dua uas yuav ua rau cov neeg ua haujlwm lom lom, xws li cov tshuaj tsw qab hydrocarbons, halogenated hydrocarbons, ammonia (amines), ethers, cawv, lipids, thiab lwm yam., PID photoionization detectors yuav tsum tau xaiv los ntawm combustible gas detectors, vim qhov no yuav ua rau tus kheej raug mob los yog tuag. Yog tias cov roj hom npog cov roj av saum toj no, xaiv cov khoom siv hluav taws xob sib xyaw yuav ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.
2. Txheeb xyuas qhov xwm txheej siv
(1) Tsau roj ntes
Qhov no yog ib qho khoom siv feem ntau siv hauv kev tsim khoom thiab kev tsim khoom. Nws tuaj yeem ntsia tau rau ntawm cov ntsiab lus tshwj xeeb txhawm rau txheeb xyuas cov pa paug tshwj xeeb. Tsau detectors feem ntau muab faib ua ob hom. Qhov kev soj ntsuam kuaj pom muaj li ntawm cov sensors thiab cov khoom sib kis tau nruab rau ntawm qhov chaw kuaj pom, thiab cov cuab yeej thib ob uas muaj cov khoom siv hluav taws xob, lub zog hluav taws xob, thiab cov khoom siv lub tswb raug teeb tsa rau hauv qhov chaw nyab xeeb rau kev saib xyuas yooj yim. Tsau roj ntes tau zoo dua rau qhov kev ruaj ntseg txuas ntxiv thiab mus sij hawm ntev uas yuav tsum tau muaj rau kev tshawb pom ntawm cov txheej txheem thiab thev naus laus zis. Nws kuj yuav tsum tau xaiv raws li hom thiab concentration ntawm cov pa roj, thiab yuav tsum tau them nyiaj mloog mus rau kev txhim kho lawv nyob rau hauv feem ntau yuav xau qhov chaw ntawm ib tug tshwj xeeb roj, xws li xaiv qhov siab zoo rau sensor installation raws li qhov tshwj xeeb. lub ntiajteb txawj nqus.
(2) Portable roj ntes
Vim lub lag luam yooj yim thiab compact loj ntawm portable instruments, lawv tuaj yeem nqa mus rau ntau qhov chaw sib txawv. Lub ntes ntawm electrochemical sensors yog siv los ntawm alkaline roj teeb thiab tuaj yeem siv tsis tu ncua rau 1000 teev; Cov hom tshiab ntawm cov khoom siv hluav taws xob hluav taws xob, PID photoionization detectors, thiab cov khoom siv hluav taws xob sib xyaw siv cov roj teeb uas siv tau (qee tus twb tau siv cov roj teeb tsis nco qab nickel hydrogen lossis lithium-ion roj teeb, ua rau lawv feem ntau tuaj yeem ua haujlwm tsis tu ncua rau ze li 12 teev. Yog li ntawd, xws li cov twj paj nruag, lawv yog nce dav siv nyob rau hauv ntau yam factories thiab kev noj qab haus huv departments.
